VB.NET overload default functionality when user clicks the X (Close Program)

Question

How do I go about overriding the default functionality when a user clicks the X in a VB.NET form-based application?

I am currently handling the MyBase.Closing event.

Re your other comments; doing anything before the event has fired would be premature; after all, some other code might cancel the close, and you'd be left with a scuppered form. Personally, I'd be tempted to override OnClosed; not much of a VB head, but in C#:

    protected override void OnClosing(CancelEventArgs e)
    {
        // check OK to close (save/cancel etc)
        base.OnClosing(e);
    }
    protected override void OnClosed(EventArgs e)
    {
        // your code here
        base.OnClosed(e);
        // or here
    }
